Optimal sequence memory in driven random networks

J Schuecker, S Goedeke, M Helias - Physical Review X, 2018 - APS
Autonomous, randomly coupled, neural networks display a transition to chaos at a critical
coupling strength. Here, we investigate the effect of a time-varying input on the onset of chaos …

[HTML][HTML] The correlation structure of local neuronal networks intrinsically results from recurrent dynamics

M Helias, T Tetzlaff, M Diesmann - PLoS computational biology, 2014 - journals.plos.org
Correlated neuronal activity is a natural consequence of network connectivity and shared
inputs to pairs of neurons, but the task-dependent modulation of correlations in relation to …

Computational neuroscience: Mathematical and statistical perspectives

…, T Fukai, S Grün, MT Harrison, M Helias… - Annual review of …, 2018 - annualreviews.org
Mathematical and statistical models have played important roles in neuroscience, especially
by describing the electrical activity of neurons recorded individually, or collectively across …

[HTML][HTML] A unified view on weakly correlated recurrent networks

…, T Tetzlaff, M Diesmann, M Helias - Frontiers in computational …, 2013 - frontiersin.org
The diversity of neuron models used in contemporary theoretical neuroscience to investigate
specific properties of covariances in the spiking activity raises the question how these …

[HTML][HTML] PyNEST: a convenient interface to the NEST simulator

JM Eppler, M Helias, E Muller, M Diesmann… - Frontiers in …, 2009 - frontiersin.org
The neural simulation tool NEST (http://www.nest-initiative.org) is a simulator for heterogeneous
networks of point neurons or neurons with a small number of compartments. It aims at …

[HTML][HTML] Decorrelation of neural-network activity by inhibitory feedback

T Tetzlaff, M Helias, GT Einevoll, M Diesmann - 2012 - journals.plos.org
Correlations in spike-train ensembles can seriously impair the encoding of information by
their spatio-temporal structure. An inevitable source of correlation in finite neural networks is …

[HTML][HTML] Spiking network simulation code for petascale computers

…, T Fukai, A Morrison, M Diesmann, M Helias - Frontiers in …, 2014 - frontiersin.org
Brain-scale networks exhibit a breathtaking heterogeneity in the dynamical properties and
parameters of their constituents. At cellular resolution, the entities of theory are neurons and …

[HTML][HTML] Extremely scalable spiking neuronal network simulation code: from laptops to exascale computers

J Jordan, T Ippen, M Helias, I Kitayama… - Frontiers in …, 2018 - frontiersin.org
State-of-the-art software tools for neuronal network simulations scale to the largest computing
systems available today and enable investigations of large-scale networks of up to 10% of …

[HTML][HTML] Run-time interoperability between neuronal network simulators based on the MUSIC framework

M Djurfeldt, J Hjorth, JM Eppler, N Dudani, M Helias… - Neuroinformatics, 2010 - Springer
MUSIC is a standard API allowing large scale neuron simulators to exchange data within a
parallel computer during runtime. A pilot implementation of this API has been released as …

[BOOK][B] Statistical field theory for neural networks

M Helias, D Dahmen - 2020 - Springer
Many qualitative features of the emerging collective dynamics in neuronal networks, such
as correlated activity, stability, response to inputs, and chaotic and regular behavior, can be …
